Specification of Letters Patent.

BELT-BUCKLE.

Patented Apr. 26, 1921.

Application filed March 2, 1921. Serial No. 449,196.

To all whom it may concern Be it known that I, R03? L. BoYnn, citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Belt-Buckles, of which the following is a specification.

My invention relates to buckles for waist belts, trunk straps and the like where a sure-grip, tongueless buckle is desirable; and the objects of my invention are- First, a tongueless buckle; second, sure grip without back slack; third, a spring adjusted clamping bar insuring firm contact on variable thickness. V

I attain these objects by the mechanism shown -in the accompanying drawing in which- Figure 1 is an inverted plan.

Fig; 2 is a left end elevation.

Fig. 3 is a longitudinal section of cover and latch.

Fig. at is a longitudinal section on line CD with belt in position when closed.

Fig. 5 is a side elevation of clamping bar.

Fig. 6 is an inverted plan of the same.

Fig. 7 is a side elevation of the latch.

Similar numerals refer to similar parts throughout the several views. I

The cover, 1, the sides, 2, and the locking ledges, 3, pressed from sheet metal, constitute the outer frame of my device. Holes, 4:, through the lower rear corners of the sides provide bearings for the tangs, 5, which project from the attaching plate, 6, adapted to be turned inward upon the tangs, 5, and bring a bar, 7 in contact with one end of a belt and by pressure between the bar, 7 and cover, 1, secure the buckle thereto (see Fig. 4:). A latch, also formed from sheet metal comprising bottom, 8, and sides, 9, is disposed within the outer frame and pivotally secured thereto by a rod, 10, which passes through holes, 11, in the latch and corresponding holes in the sides, 2, and is riveted outside thereof. An aperture, 12,

is located through the walls, 9, of the latch ad acent the rear ends and just forward of the holes, 11. A clamping bar, 1 1, is disposed across the latch, and tangs, 18, at both ends of the same are adapted to slide in and be guided by the apertures, 12; said apertures incline at a slight angle from the bottom, 8, toward the front end of the latch so that when the clamping bar comes into contact with a belt any strain on the belt will cause the bar to incline to the bottom. A fiat spring, 15, is disposed on the inside of the latch with one end resting 'upon the clamping bar and the other end secured to the bottom of the same by a rivet. 16. Normally the tangs, 13, on the bar, 14, rest at the bottom of the apertures, 12, and the spring, 15, is a distance from the member, 8, over the bar; but when the latch is closed and the bar raised by contact with a belt, a spring pressure is produced which keeps the bar in contact with belts of variable thickness. The said latch is locked in closed position by passing beyond projections, 3, when the resilience of the sides, 2, of the cover will hold same until a strain is applied to the buckle cover. The edge of the bar where it comes into contact with the belt may be serrated if desired.

Having thus described my invention, I claim:

In a device of the kind described, a cover with a latch pivotally secured within the same; a spring actuated clamping bar disposed in guides through each side of said latch, said guides disposed at an acute angle to the bottom in the direction of the pivots; and a means for securing the cover to one end of a belt.

In testimony whereof I aiiix my signature in the presence of two subscribing witnesses.

ROY L. BOYER.
